ABSTRACT

The invention relates to novel deodorizing preparations with a synergistically improved performance. The novel preparations contain (a) dialkyl carbonates, (b1) antiperspirants, (b2) esterase inhibitors, (b3) bactericidal or bacteriostatic active substances and/or (b4) perspiration-absorbing substances.

FIELD OF THE INVENTION

[0001] This invention relates to deodorizing preparations containingdialkyl carbonates, antiperspirants, esterase inhibitors, bactericidalor bacteriostatic agents and/or perspiration-absorbing substances and totheir use for the production of deodorizing preparations.

PRIOR ART

[0002] In the field of personal care, deodorants are used to eliminateunpleasant body odors. Examples of such substances are aluminiumcompounds, such as aluminium sulfate or aluminium chlorhydrate, zincsalts and citric acid compounds. Since the problem of odor inhibitionhas by no means been completely solved, there is still a need for newpreparations in which the deodorants can readily be emulsified andincorporated. This is intended to ensure more uniform distribution ofthe deodorants and, hence, an improvement in their effect, i.e.minimization of perspiration and a reduction in odor formation. Inaddition, the feeling of the skin after the application of deodorantsshould be improved and greater stability of the final formulationsachieved in relation to the prior art.

[0003] Accordingly, the problem addressed by the invention was toprovide such products.

DESCRIPTION OF THE INVENTION

[0004] The present invention relates to deodorizing preparationscontaining

[0005] (a) dialkyl carbonates corresponding to formula (I):

[0006] in which R¹ is a linear alkyl and/or alkenyl group containing 6to 22 carbon atoms, a 2-ethylhexyl, isotridecyl or isostearyl group or agroup derived from a polyol containing 2 to 15 carbon atoms and at leasttwo hydroxyl groups, R² has the same meaning as R¹ or is an alkyl groupcontaining 1 to 5 carbon atoms and n and m independently of one anotherstand for 0 or numbers of 1 to 100,

[0007] (b1) antiperspirants,

[0008] (b2) esterase inhibitors,

[0009] (b3) bactericidal or bacteriostatic agents and/or

[0010] (b4) perspiration-absorbing substances.

[0011] The use of antiperspirants, esterase inhibitors (for exampletriethyl citrate), bactericidal agents (for example chitosan) and/orperspiration-absorbing substances for the production of deodorizingand/or perspiration-inhibiting compositions is known from the prior art.It has surprisingly been found that the emulsification properties ofdeodorizing preparations of the substances mentioned above can besignificantly improved by dialkyl carbonates. Of particular advantage isthe more homogeneous distribution of the deodorants where dialkylcarbonate is present which leads to an improvement in the effect andhence to a minimization of perspiration and a reduction in odorformation. In addition, the feeling on the skin in terms of smoothness,powderiness, absorption behavior and dryness is improved. The greaterstability of the final formulations has proved to be another advantage.In the case of suspension sticks and “suspension soft solids”,transparent application (“rub-off”) is facilitated.

[0012] Dialkyl Carbonates

[0013] Dialkyl carbonates which form component (a) are basically knowncompounds even through some of the claimed compounds are being describedfor the first time in the present specification. Basically, they may beprepared by transesterification of dimethyl or diethyl carbonate withthe hydroxy compounds mentioned using known methods. A review of thesemethods can be found, for example, in Chem. Rev. 96, 951 (1996). Dialkylcarbonates corresponding to formula (I) which are particularly suitablefor solving the stated problem satisfy one of the followingrequirements:

[0014] (A) R¹ is a linear alkyl group containing 8 to 18 carbon atoms ora 2-ethylhexyl group and R² has the same meaning as R¹ or representsmethyl;

[0015] (B) R¹ is a linear alkyl group containing 12 to 18 carbon atoms,R² has the same meaning as R¹ or represents methyl and n and m stand fornumbers of 1 to 10;

[0016] (C) R¹ is a residue of a polyol selected from the groupconsisting of glycerol, alkylene glycols, technical oligoglycerolmixtures, methylol compounds, lower alkyl glucosides, sugar alcohols,sugars and aminosugars and R² has the same meaning as R¹ or represents alinear or branched alkyl group containing 8 to 12 carbon atoms ormethyl.

[0017] Typical examples of dialkyl carbonates belonging to the twogroups (A) and (B) are complete or partial transesterification productsof dimethyl and/or diethyl carbonate with caproic alcohol, caprylicalcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol,isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmitoleylalcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidylalcohol, petroselinyl alcohol, linolyl alcohol, linolenyl alcohol,elaeostearyl alcohol, arachyl alcohol, gadoleyl alcohol, behenylalcohol, erucyl alcohol and brassidyl alcohol and the technical mixturesthereof formed, for example, in the high-pressure hydrogenation oftechnical methyl esters based on fats and oils or aldehydes fromRoelen's oxosynthesis and as monomer fraction in the dimerization ofunsaturated fatty alcohols. The transesterification products of thelower carbonates with the alcohols mentioned in the form of theiradducts with 1 to 100, preferably 2 to 50 and more preferably 5 to 20moles of ethylene oxide are also suitable. Di-n-octyl carbonates arepreferred

[0018] The carbonates of group (C) are being described for the firsttime in the present specification. They are compounds which are obtainedby complete or partial transesterification of dimethyl and/or diethylcarbonate with polyols. Polyols suitable for the purposes of theinvention preferably contain 2 to 15 carbon atoms and at least twohydroxyl groups. Typical examples are

[0019] glycerol;

[0020] alkylene glycols such as, for example, ethylene glycol,diethylene glycol, propylene glycol, butylene glycol, hexylene glycoland also polyethylene glycols with an average molecular weight of 100 to1,000 dalton;

[0021] technical oligoglycerol mixtures with a degree ofself-condensation of 1.5 to 10, for example technical diglycerolmixtures with a diglycerol content of 40 to 50% by weight;

[0022] methylol compounds such as, in particular, trimethylol ethane,trimethylol propane, trimethylol butane, pentaerythritol anddipentaerythritol;

[0023] lower alkyl glucosides, more particularly those containing 1 to 8carbon atoms in the alkyl group, for example methyl and butyl glucoside;

[0024] sugar alcohols containing 5 to 12 carbon atoms such as, forexample, sorbitol or mannitol;

[0025] sugars containing 5 to 12 carbon atoms such as, for example,glucose or sucrose and

[0026] aminosugars such as, for example, glucamine.

[0027] This reaction can of course not only result in replacement of amethyl or ethyl group by a polyol residue, it also gives a mixture inwhich several hydroxy groups or even all the hydroxyl groups of thepolyol are attached to carbonate groups so that an oligomeric orpolymeric net structure may even be obtained. In the context of theinvention, compounds of this type are also meant to fall within thescope of general formula (I).

[0028] The preparations according to the invention may contain thedialkyl carbonates in quantities of 1 to 80, preferably 5 to 50 and moreparticularly 10 to 30% by weight, based on the solids content.

[0029] Antiperspirants

[0030] The antiperspirants of component (b1) are salts of aluminium,zirconium or zinc. Suitable antihydrotic agents of this type are, forexample, aluminium chloride, aluminium chlorohydrate, aluminiumdichlorohydrate, aluminium sesquichlorohydrate and complex compoundsthereof, for example with 1,2-propylene glycol, aluminiumhydroxyallantoinate, aluminium chloride tartrate, aluminium zirconiumtrichlorohydrate, aluminium zirconium tetrachlorohydrate, aluminiumzirconium pentachlorohydrate and complex compounds thereof, for examplewith amino acids, such as glycine. Aluminium chlorohydrate, aluminiumzirconium tetrachlorohydrate, aluminium zirconium pentachlorohydrate andcomplex compounds thereof are preferably used. In addition,antiperspirants may contain typical oil-soluble and water-solubleauxiliaries in relatively small amounts. Oil-soluble auxiliaries such asthese include, for example,

[0031] inflammation-inhibiting, skin-protecting or pleasant-smellingessential oils,

[0032] synthetic skin-protecting agents and/or

[0033] oil-soluble perfume oils.

[0034] The preparations according to the invention may contain theantiperspirants in quantities of 1 to 50, preferably 5 to 30 and moreparticularly 10 to 25% by weight, based on the solids content.

[0035] Esterase Inhibitors

[0036] Where perspiration is present in the underarm region,extracellular enzymes—esterases, mainly proteases and/or lipases—areformed by bacteria and split the esters present in the perspiration,releasing odors in the process. Esterase inhibitors of component (b2)are preferably trialkyl citrates, such as trimethyl citrate, tripropylcitrate, triisopropyl citrate, tributyl citrate and, in particular,triethyl citrate (Hydagen® CAT, Cognis GmbH, Düsseldorf, FRG). Esteraseinhibitors inhibit enzyme activity and thus reduce odor formation. Thefree acid is probably released by the cleavage of the citric acid esterand reduces the pH value of the skin to such an extent that the enzymesare inactivated by acylation. Other esterase inhibitors are sterolsulfates or phosphates such as, for example, lanosterol, cholesterol,campesterol, stigmasterol and sitosterol sulfate or phosphate,dicarboxylic acids and esters thereof, for example glutaric acid,glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid,adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid andmalonic acid diethyl ester, hydroxycarboxylic acids and esters thereof,for example citric acid, malic acid, tartaric acid or tartaric aciddiethyl ester, and zinc glycinate.

[0037] The preparations according to the invention may contain theesterase inhibitors in quantities of 0.01 to 20, preferably 0.1 to 10and more particularly 0.5 to 5% by weight, based on the solids content.

[0038] Bactericidal or Bacteriostatic Agents

[0039] Typical examples of suitable bactericidal or bacteriostaticagents of component (b3) are, in particular, chitosan andphenoxyethanol. 5-Chloro-2-(2,4-dichlorophenoxy)-phenol which ismarketed under the name of Irgasan® by Ciba-Geigy, Basle, Switzerland,has proved to be particularly effective.

[0040] Cosmetic deodorants counteract, mask or eliminate body odors.Body odors are formed through the action of skin bacteria on apocrineperspiration which results in the formation of unpleasant-smellingdegradation products. Accordingly, deodorants contain active principleswhich act as germ inhibitors, enzyme inhibitors, odor absorbers or odormaskers. Basically, suitable germ inhibitors are any substances whichact against gram-positive bacteria such as, for example,4-hydroxybenzoic acid and salts and esters thereof,N-(4-chlorophenyl)-N′-(3,4-dichlorophenyl)-urea,2,4,4′-trichloro-2′-hydroxydiphenylether (triclosan),4-chloro-3,5-dimethylphenol,2,2′-methylene-bis-(6-bromo-4-chlorophenol), 3-methyl-4-(1-methylethyl)-phenol, 2-benzyl-4-chlorophenol,3-(4-chlorophenoxy)-propane-1,2-diol, 3-iodo-2-propinyl butyl carbamate,chlorhexidine, 3,4,4′-trichlorocarbanilide (TTC), antibacterialperfumes, thymol, thyme oil, eugenol, clove oil, menthol, mint oil,farnesol, phenoxyethanol, glycerol monocaprate, glycerol monocaprylate,glycerol monolaurate (GML), diglycerol monocaprate (DMC), salicylicacid-N-alkylamides such as, for example, salicylic acid-n-octyl amide orsalicylic acid-n-decyl amide.

[0041] Suitable odor absorbers are substances which are capable ofabsorbing and largely retaining the odor-forming compounds. They reducethe partial pressure of the individual components and thus also reducethe rate at which they spread. An important requirement in this regardis that perfumes must remain unimpaired. Odor absorbers are not activeagainst bacteria. They contain, for example, a complex zinc salt ofricinoleic acid or special perfumes of largely neutral odor known to theexpert as “fixateurs” such as, for example, extracts of ladanum orstyrax or certain abietic acid derivatives as their principal component.Odor maskers are perfumes or perfume oils which, besides theirodor-masking function, impart their particular perfume note to thedeodorants. Suitable perfume oils are, for example, mixtures of naturaland synthetic perfumes. Natural perfumes include the extracts ofblossoms, stems and leaves, fruits, fruit peel, roots, woods, herbs andgrasses, needles and branches, resins and balsams. Animal raw materials,for example civet and beaver, may also be used. Typical syntheticperfume compounds are products of the ester, ether, aldehyde, ketone,alcohol and hydrocarbon type. Examples of perfume compounds of the estertype are benzyl acetate, p-tert.butyl cyclohexylacetate, linalylacetate, phenyl ethyl acetate, linalyl benzoate, benzyl formate, allylcyclohexyl propionate, styrallyl propionate and benzyl salicylate.Ethers include, for example, benzyl ethyl ether while aldehydes include,for example, the linear alkanals containing 8 to 18 carbon atoms,citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde,hydroxy-citronellal, lilial and bourgeonal. Examples of suitable ketonesare the ionones and methyl cedryl ketone. Suitable alcohols are anethol,citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethylalcohol and terpineol. The hydrocarbons mainly include the terpenes andbalsams. However, it is preferred to use mixtures of different perfumecompounds which, together, produce an agreeable fragrance. Othersuitable perfume oils are essential oils of relatively low volatilitywhich are mostly used as aroma components. Examples are sage oil,camomile oil, clove oil, melissa oil, mint oil, cinnamon leaf oil,lime-blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanumoil, ladanum oil and lavendin oil. The following are preferably usedeither individually or in the form of mixtures: bergamot oil,dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol,α-hexylcinnamaldehyde, geraniol, benzyl acetone, cyclamen aldehyde,linalool, Boisambrene Forte, Ambroxan, indole, hedione, sandelice,citrus oil, mandarin oil, orange oil, allylamyl glycolate, cyclovertal,lavendin oil, clary oil, β-damascone, geranium oil bourbon, cyclohexylsalicylate, Vertofix Coeur, Iso-E-Super, Fixolide NP, evernyl, iraldeingamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide,romilat, irotyl and floramat.

[0042] The preparations according to the invention may contain thebactericidal or bacteriostatic agents in quantities of 0.01 to 5% byweight and preferably 0.1 to 2% by weight, based on the solids content.

[0043] Perspiration-Absorbing Substances

[0044] Suitable perspiration absorbers which form component (b4) aremodified starch such as, for example, Dry Flo Plus (National Starch),silicates, talcum and other substances of similar modification whichappear suitable for absorbing perspiration.

[0045] The preparations according to the invention may contain theperspiration-absorbing substances in quantities of 0.1 to 30% by weight,preferably 1 to 20% by weight and more particularly 5 to 10% by weight,based on the solids content.
